REGULATING MEANS FOR INTERNAL-COMBUSTION ENGINES.

Application filed September 14, 1920. Serial No, 410,277.

To all whom it may concern:

Be it known that I, EDW'ARD H. BELDEN, a citizen of the United States, residing at T- ledo, county of Lucas, State of Ohio, have invented certain new and useful Improvements in Regulating Means for Internal- Combustion Engines, of which I declare the following to be a full, clear, and exact description.

My invention relates to improvements in speed regulators and is particularly directed. to a construction for operating the throttle for adjusting the spark and controlling the forced feed lubricating system.

One object of the invention is to provide a new and improved means thru. which the spark is controlled.

Another object of the invention is to provide a new and improved means for operating the throttle.

Another object of the invention is to provide an improved mechanism by which the throttle is operated and the feed lubricating system is controlled simultaneously.

Another object is the provision of a novel connection between the steering wheel lever and the throttle operating mechanism which will permit further operation of that mechanism toward the open throttle position independently by means of a foot accelerator.

Another object of the invention is to provide a unitary structure through which the spark or throttle may be controlled.

In still another object of the invention provision is made for a unitary structure which permits of the operation of the throttle and the forced feed lubricating system control by the accelerator pedal with out disturbing the throttle lever on the steer-- ing wheel.

Further objects of the invention relate to economies of manufacture and details of construction as will hereinafter appear from the description. to follow:

The objects of the invention are accom-.

plished in one instance by the devices and means described in the following specification, but it is evident that the same may be varied without departing from the scope of the invention as pointed out in the appended claims. A structure constituting one embodiment of the invention which may be the preferred is illustrated in the accompanying drawings forming a part of the specifications, in which:

Figure I is a perspective view of the speed regulator mechanism as applied to an internal combustion engine.

Figure II is a side elevation of the steering post partly in section showing the operating rods for the cams.

Figure III is a fragmentary rear view showing the bell crank levers in engagement with the operating cams.

Figure IV is a fragmentary end view of the same construction shown in Figure III.

In reducing my invention to practice I provide a hollow steering post 1 having a steering wheel 2 mounted on one end and provided with the usual operating levers 3 and 4 for the hollow rods 5 and 6 located within the post 1 to control the spark and throttle. Mounted on the lower ends of these rods are cams 7 and 8 which engage rollers 9 and 10 on the lower free arms 11 and 12 of bell crank levers 13 and 14, respectively. The upper arms 15 and 16 of the levers are in staggered relation to the lower arms 11 and 12.

The bell-crank levers are pivoted on a spindle 17 which is fixed in position on a bracket 18. A split sleeve 19 mounted on the lower end of the steering post by means of flanges 20 and 21 and bolts 22 and 23 is made integral with the bracket 18.

The lever 13 is resiliently held in a predetermined position by a spring 24. The upper arm 15 of the lever 13 is perforated at 25 and provided with a pintle 26 pivoted in the perforation. The pintle carries a rod 27 fixed at one end to the pintle. the other end being bent and pivoted at 28 to the operating lever 29 of the timer distributor 30.

The upper arm 16 of the lever 14 is connected at 31 to a reciprocating rod 32 which is likewise adjustably connected at 33 with a crank 34 of the rock shaft 35. The rock shaft 35 loosely mounted in brackets 36 and 37 is operated by means of the accelerator pedal 38 which is in the form of a bell-crank lever having an arm 39 fixed to the rock shaft and another arm 40 having a pivotal roiniection at 41. with the crank arm 42 ot the rod 43. The other end of the rod is adjustably connm'tod to a crank a l. of a loosely mounted shaft 45 operating a ram 416 "h engages the stem 47 valve that trols a bypass in the teed lubricating system to relieve 7c in that svstenz. A resilient means 48 returns the pe al 38 and the bell-crank lcvcr 14 to their normal positions.

Sin arm 49 tirmly mounteiil on said shaft 35 pivotally connected at 50 with an ad justable clement 5.1. on one end of a reciprocatingrrod The other end 53 ot this rod is pivoted on a pin L carried by a lever 55 which operates the throttle o? the rar buretor.

The operation of my device is as follows:

When the spark lever 1-3 is operated the hollow rod 5 (misses the cam T to engage with the roller 9 torcing the arm Ill upwardly and through the arm the timer distrilmtor 29- will adjust the timing of the spark.

When the throttle lever 4. is operated the hollow rod 6 causes the cam 8 to engage with the roller 10 forcing the arm 12 upwardly. The other arm 16 of the lever is operated reci nocating the rod 32, moving the lever 34 ownwardly and revolving the shaft 35. The arm H) on the shaft 35 and the arm 55 through the connecting rod 52 are rocked, opening more or less the throttle valve.

When the throttle is adjusted in this manner thcarm l0 of the accelerator pedal 38 is rocked recipiiocating the rod l2; and revolving the shaft 4-5 through the arm l t. The cam 46 engages the stem at? of a valve in the by-pass of the forced :tced lubricating system, closing said valve more or less thus creating a pressure in the system. The valve and by-pass are not illustrated specifically because. their details torm no part otthe present invention. The sprin 4L8 tends to return thrparts to normal pus ion,

WVhen the accelerator pedal 38 is depressed the shaftfifi is revolved and the crank arm 34- rocks the arm 16 of the lever l l: through the mediumof the rod 52 and raises the lower arm 12 and its roller 10 out of cngaging position with the cam \Vhile the lever 14 is in this position an operation of the throttle lever on the steering wheel may have no effect on the throttle valve. The lower arm 40 ot the depressed pedal 38 has been moved :toij'wardly and through its connection with the shaft causes the cam 4-6 to depress the stem 4L7, closing'the valve .in

the by-pass'ot' the forced feed lubricating,

system. The upper arm 39 of the compressed pedal 38 has revolved the shaft rocking the arm 49 rearwardly and through its connection with the lever 3:") has opened more or less the throttle valve.

It will now be apparent from the description that depressing the accelerator pedal will not. disturb any previous position at which the throttle lever on the steering wheel may have been set before the accelerator pedal was depressed and the operator of the car after having released the pedal, may manually adjust the throttle from its former position by the lever on the steering wheel. The throttle valve is returned to the position set by the throttle lever on the steering wheel by means of the spring 4L8.

hile l have shown and described my invention in more or less detail as being embodied in certain precise :l'orms, I do not desire or intend it to bev limited thereto, as on the contrary; my invention contemplates broadly all proper changes as well as the OIIllSSlOH ol' the material elements and the substitution of equivalents as circumstances may suggest.
